Overview Selecting the right oxidant can have a major impact on treatment efficiency, operational safety, and overall cost. For environmental engineers, utility managers, and operators, understanding the key differences between potassium and sodium permanganate is essential. This guide demystifies the choice between these two powerful oxidants—helping you make the best decision for your unique process. …
Helping Mining Operations Achieve Compliance, Sustainability, and ESG Goals Overview Mining operations face complex water treatment challenges. Wastewater streams often contain dissolved metals (iron, manganese, etc.), cyanide, acidity, and suspended solids — each with its own regulatory and environmental risks. As global discharge limits tighten, site managers and compliance officers are seeking reliable, field-proven solutions …
Prepare for the 5th Liter Sample The U.S. Environmental Protection Agency (EPA) has made important updates to the Lead and Copper Rule (LCRR), and one change in particular—the adoption of the 5th liter sampling protocol—is poised to significantly impact how water systems across the country monitor and manage lead levels in drinking water. What’s Changing? …
Carus recently partnered with Illinois Valley Community College’s Continuing Education Department to help bring Science FUN’damentals to life—a two-hour summer camp that encourages hands-on learning and scientific exploration for kids ages 6–8. Led by Carus chemist Akila and supported by Rachel, a former Carus chemist who continues to volunteer with the program, the session introduced kids to foundational science topics …
Each summer, a group of local sixth graders trade typical campfire stories for lab goggles, test tubes, and hands-on experiments. The Carus Summer Science Camp has become a tradition in the Illinois Valley—one that turns curiosity into confidence and science into something students can see, touch, and launch into the sky. Now in its 23rd …
Ethylene oxide (EtO) is widely used to sterilize medical devices and equipment that can’t tolerate high temperatures or moisture. While highly effective as a sterilant, EtO is also classified as a carcinogen and must be tightly controlled to protect public health and comply with evolving environmental regulations. In response, hospitals, laboratories, and sterilization service providers …
Volatile Organic Compounds (VOCs) are a major concern in many industrial and commercial environments. These organic chemicals easily vaporize into the air, often originating from solvents, fuels, paints, and industrial processes. Without effective treatment, VOCs contribute to poor indoor air quality and can present serious health and environmental risks. Facility managers and engineers need reliable, …
In many industrial environments, ozone isn’t just a byproduct—it’s a hazard. From water treatment facilities to electronics manufacturing and printing plants, ozone can be emitted during routine processes. When not properly mitigated, these emissions pose serious risks to both worker health and environmental safety. Industrial plant managers, environmental engineers, and compliance officers alike are searching …
At Carus, protecting the environment is at the core of our mission. This April, we marked Earth Month with a variety of activities that supported sustainability, education, and community engagement — with efforts continuing into May. Here’s a look at how we came together to make a difference: Earth Month Kickoff We began the month …
Table of Contents The Biden-Harris Administration recently announced a significant milestone in chemical safety, finalizing rules to ban trichloroethylene (TCE) and restrict perchloroethylene (PCE) under the Toxic Substances Control Act (EPA, 2024). These two chemicals, long used in industries such as dry cleaning, adhesives, and degreasing, have been linked to severe health risks, including cancer …
